As children head back to class this year, school officials are working closely with Bristol police and going over security plans with all faculty and staff.

"There are some measures to better secure the front and rear entrances to all of the schools," Solek said, "a buzzer system so that everyone entering and exiting the building is monitored both in person and on camera. A lot of those things we already have in place, but we're adding some more this year as well."

Solek said there were also some additional cameras, other surveillance systems and some prevention measures in place.

Police said there are still two threats from last year that remain unsolved, both at Bristol Eastern High School.

One of them was scribbled on a piece of furniture, but there are no leads on a suspect. The other was called in through some sort of electronic device, but school leaders do not believe that one came from a student.

Solek said the bottom line was these scares were expensive for the town and state, and would not be tolerated.
